Looking for a gym

I am looking for a ladies gym. I am not interested in Curves because I like to take cardio classes and not just use the machines. I have been to Lucille Roberts but I am wondering if there is anything better out there.

I live in Nassau County and work in NYC.

I go to Lucille just because the prices are so good, I' m a class taker too...
I just saw a commercial though for Bally's running a $20/month plan which I think is great for them.

Dur, Bally's is not ladies only though. I can't think of any besides Curves or Lucille for that..or Ladies Fitness Express but that is basically a Curves knockoff I think.
